To date, Joel Brandon Jr. is the biggest baby delivered in the U.S. in 2013.

Baby JJ came into the world six months ago a week early.

JJ's mother, Sara Brandon, said big babies run in her family.

Doctors said Sara's Type 1 diabetes likely contributed to JJ's size.

"The last ultrasound showed around 11 pounds so we thought, yeah, we'll probably have a 10 maybe 11-pound baby at the most," said Sara Brandon. "And then, when he came out and put him on the scale and it said 14, we were ALL like really shocked."
